To @ZZ whom t may concern,.-

. Be it known that I, JOHN R. BECKETT, J r., of Bradford, in the countyof Essex and State of Massachusetts, have invented certain new anduseful Improvements in Seam and Scallop Turning Machines, of which thefollowing is a specification.

This inventionrelates to that class of machines known as turning orbeading machines, Io the object and purposeof which are to turn and pushout the seams of leather or other material. These machines are mostusually employed for turning and pushing out the seams between a pieceof leather and its lining, and r 5 particularly where the lined leatheris used for shoe uppers. These machines are also especially useful inturning or pushing out the scallops of the button-nies of ladies andmisses shoes. As is well known, the lining is sewed to the leather whenthe leather is wrong side out, so that it is necessary to turn theleather and lining in order to bring the right side of the leather out,and these-ma chines are employed for this purpos The z 5 turningmachines are also customarily employed in connection with a hammer forhammering the seams flat,which hammering, properly speaking, constitutesthe beading operation. Such prior seam and scallop turning machines havealso been heretofore made with rapidly movable and driven turningblades, fingers, irons, or turners for the purpose of facilitating theturning of the leather. Now the present invention relates more 3 5particularly to the construction of the turning element or elements ofthe turning machine which enters between a piece of material and itslining or into a scallop; to the character and direction of the movementimparted thereto, and the mechanism for effecting and imparting saidmovement; and the objects of the present improvements are to simplifyand cheapen the construction of the machine, to increase the rapidity,effectiveness, and quality of the work done, to abolish or reduce to aminimum the jar upon the attendant or operative, to facilitate thereplacement of the turning element or elements in case of undue wear,and to prevent the cut- 5o ting or rupturing of the leather, the lining,or

the threads uniting the same.

The turning element of the machine which enters between the material andits lining or into a scallop will hereinafter be termed the seam orscallop turner.

The present improvements are illustrated in the accompanying drawings,wherein- Figure 1, is a front view of the improved turning machine. Fig.2, is a side view thereof. Fig. 3, is a horizontal section in a planeindicated by the line 3 3 in Fig. 2. Fig. 4, is an enlarged front View,Fig. 5, an enlarged side view, and Fig. G an enlarged plan view of theseam or scallop turner. Fig.

Fig. 9, is a front view ofthe turning machine having a modified driving mech- 7o anisrn for theseam or scallop turner. Fig. 10,

is a detail View showing the connection between the seam or scallopturner and the driving pitman. Fig. l1, shows a modification of theconnection shown in Fig. lO. Fig. l2, is a front view of the turningmachine having a seam or scallop turner with a modified motion and acorrespondinglymodified operating mechanism.

Referring first to the preferred construc- 8o tion shown in Figs. l, to6, inclusiveyA, is a suitable supporting bed-plate, havingaverticalstandard B rising therefrom, and journal-boxes C, D, at the base of thestandard, said parts being preferably cast of metal in a 8 5 singlepiece. The vertical standardB has at its upper end aforwardly-projecting nose d, through which extends avertically-extending and longitudinally-adjustable stem E, which at itsupper end carries the turning 9o element F. The lower part of the stem Eis screw-threaded, and it. is adj ustably secured to the nose ct bymeans of upper and lower nuts b and c located respectively above andbelow the nose o. The upper end of the stem 9 5 E is split or forked byan open slot CZ to receive the seam or scallop turner F, which consistsof a wheel or disk which is journaled upon the stern E by an arbor c towhich the disk F is secured, said arbor c extending roo transversely tothe slot d and turning in open bearings ff formed in the upper end ofthe stem E. The disk F has a peripheral groove g, and its periphery isalso on both sides of the groove girregular or scalloped, as shown inFigs. l, and 4. The rotatively-mounted seam or scallop turner F ispositively rotated, but the rotation in this preferred construction isback and forth through a portion only of a circle, the extent of thepartial rotation or oscillation being through about ninety degrees ofarc. p

The operating instrumentalities for the seam or scallop turner F are asfollowsz-The main drive shaft G extends longitudinally through thebearing O and has at its rear end fast and loose grooved pulleys h and1I, by means of which the shaft G is rotated from any convenient sourceof power. At its forward end the shaft G has an eccentric j, surroundingwhich is an eccentric sleeve or strap 7c at one end of a link I-I whichat its other end has a second sleeve or strap Z which in turn embraces acrank stud or pin fm. fixed eccentrically to an oscillating disk orwheel I, xed upon the front end of arock-shaft J extending horizontallythrough the bearing D. The wheel I is oscillated back and forth by meansof the rotating eccentric j and the link H. The wheel I has a groovedperiphery, and its oscillating movement is imparted to the seam orscallop turner F by means of a drive belt K which extends around and islocated in the peripheral grooves of the wheel I and seam or scallopturner F. This drive belt K is preferably formed of inelastic materialsuch as a round strip of cat-gut, and its opposite ends are secured by asuitable clamp n. The diameter of the wheel I is considerably greaterthan that of the seam or scallop turner F, so that a slight throw of theeccentric j is sufficient to give the desired extent of oscillation totne seam or scallop turner F. The offsetting or forward projecting ofthe nose ct enables the seam or scallop turner F to be located directlyabove the oscillating wheel I. The vertical adjustment of the stem E,enables it to act as a belt tightener for tightening the drive belt K.The depth of the peripheral groove g in the seam or scallop turner F isgreater than the diameter of the drive belt K, so that no portion of thedrive belt projects above the working edge of the seam or scallopturner.

In using the machine the drive shaft is driven very rapidly, say twelvehundred revolutions a minute, whereby an equal number of completeback-and-forth rotations or oscillations is imparted to the seam orscallop turner. The seam is turned by passing the lined material overthe seam or scallop turner with the seam or scallop turner between theliningand the outer material, and holding the seam upon the seam orscallop turner. The rapid movement of the seam or scallop turner pushesand smoothes out the seam, the irregular or scalloped edge materiallycontributing to the result. The size of the seam or scallop turner issuch that it readily enters between a piece 0f material and its liningor into the scallops of shoe ies so that its working edge is presentedto the seam thereof.

The separation of the outer edges of the seam or scallop turner F by thebelt groove g, enables the seam itself to enter the groove g and theouter edges of the seam or scallop turner F to pass on opposite sides ofthe seam, thus insuring a smooth and even edge.

In case excessive wear upon the seam or scallop turner renders the sameso sharp as to endanger the cutting of the material operated upon, theseam or scallop turner can be readily removed and a new one substituted.

Although an irregular or scalloped seam or scallop turner is preferablyemployed, it is not essential and a smooth onelike that shown in Fig. 7,may be employed. In any case the working edge of the turner presents nosharp corners or edge which would be liable to cut or injure thematerial. By an irregular edge to the turner, I mean any variation inthe shape of the working edge from a circular edge concentric with thepivot on which the turner turns. One object of the irregularity is toprevent the seam being held with perfect steadiness upon the turner andto impart an incessant motion to the seam, whereby the smoothing andspreading of the sealn are facilitated. The attendantof the machine hassimply to hold the seam with a slight continuous pressure against theturner, and the irregularities of the working edge of theturnerimpartanincessantbutslight movement to the seam which is very effective upon theseam without unduly jarring the hands of the attendant. Nor is itessential that the groove g in the periphery of the seam or scallopturner should be greater in depth than the diameter of the driving belt,since the opposite may be the case as shown in Fig. 8, where the edge ofthe driving belt or cord K becomes the part which actually comes incontact with the seam. Noris it essential that a driving belt or cordmay be employed.

In the modiication shown in Fig. 9, a pitman L replaces the belt K, anda bell crank lever M replaces the wheel I. The pitman L may be pivotedeither within the groove g of the seam or scallop turner F as shown inFig. 10, or exterior thereto as shown in Fig. 11. Fig. 11 also showsthat the seam or scallop turner need not have a peripheral groove. Therotation imparted to the seam or scallop turner may also be a continuousrotary movement in the same direction instead of a backand-forthrotation, and such is the character of rotation in the modificationshown in Fig. 12. In this modification, the wheelI is mounted directlyupon the drive-shaft G.

The improved turning machine is usually employed, like other turningmachines, in connection with a hammer.

It will be noted that, in the preferred con- IOO IIO

struction illustrated in Figs. 1,to 6, inclusive, only the upper portionof the edge of the oscillating rotary seam or scallop turner F is theworking portion of the turner; and hence in constructing and shaping theseam or scallop turner only this working edge is material and need beconsidered. It is, however, desirable and convenient to make the seam orscallop turner as a disk with its entire periphery scalloped, since asone portion Wears the seam or scallop turner may be adjusted and afreshportion can be made the working edge. This statement is true, also, inreference to the modification shown in Figs. 9, l0, and 11.
